The PlayStation Store now has game rental listings on the site, and some released images offer an inside look on how the system may work.

An image released by Gaikai's website, shows the PS3 game Catherine is available in three forms; 1 day, 7 day, or 30 day rental. All three rentals are there for free, which indicates it may not be ready to go yet. See the image here.

According to Polygon, Sony confirmed the listings are up, but transactions can not be completed because they are not live yet.
PlayStation Now prices may have been revealed according to new concept art that is making its way around the Internet.

IGN reported, it could possibly be between $4.99 and $5.99 to rent a streamed PS3 game. The Gaikai website showed a picture featuring Uncharted 3 and Far Cry 3 with little blue PS Now triangles and a price next to them. See that image here.

IGN reported it is unclear how long these rented games will be available for, and whether the price of the listed games is correct or not. PlayStation Now is expected in North America by the end of this year, and in Europe in 2015.
